To all whom it may concern: As shown on the drawings: Be it known thatI, CHARLES L. MOORMAN, The sheet metal walls of an ice can are 7 acitizen of the United States, and a resirepresented by the numeral 6. Inthe pardent of the city of Chicago, in the county of ticular form shownin Fig. 1 each sheet 5 Cook and State of Illinios, have invented formstwo sides of the can so that two dicertain new and useful Improvementsin an agonally opposite seams 7. result. These Ice-Can Construction; andI do hereby deseams are preferably formed by folding the clare that thefollowing is a full, clear, and edges of each sheet back upon thematerial, exact description of the same, reference interlocking thehooks so formed, soldering, 60 being had to the accompanying drawings,and providing additional securing means and to the numerals of referencemarked such as rivets or looking indentations 8 to thereon, which form apart of this specificaguarantee against opening of the seam tion. aunder severe service. 7
